Hi Eric,
We have seen this with Novell. Basically, pysnmp does not like the
packets coming back from a Novell box. I have reported the problem to
pysnmp along with a test packet but I haven't heard anything back. I
haven't yet figured it out on my own.
I don't know why you would see this for a linux bux. If you can do a
manual snmpwalk of the linux box and you see these values, please let me
know.
If a box fails to respond to a batch request for OIDs, zenperfsnmp
fetches the same OIDs in individual requests to weed out the ones that
are failing.
For late-model Linuxen, you may find that the snmp server is only
exposing a very small part of the SNMP tree. I know this to be true for
Fedora Core 5.
